roadster tire pressure

[nkaminar]

35 psi is a good starting point. Roadsters need less pressure than a heavy sedan. Try reducing or increasing the pressure a little. The object is to have a good pressure patch on the road and not to have the tires get hot. Use your IR temperature gun to measure the temperature. If the pressure is too high and they will wear more in the center and too low they will wear more on the sides. The temperature should be even across the tread and not hot on the sidewalls. Temperature is related to the ambient temperature but not more than 120 F on a 80 degree day after a half hour highway run.
